I ported to GP2X (tested on my F200 with open2x firmware) some times ago a 0.70 version.
Is based on the Caanoo version by SIENCE.
Is very slow but usable...almost to test the demos included in the package.
Look here to download http://dl.openhandhelds.org/cgi-bin/gp2 ... ,0,14,2875
now i have a Pandora and i have lost interest on GP2X, so don't know if i'll build more versions for this...
